Violation of the Landau-Yang theorem from Infrared Lorentz Symmetry Breaking
M. Asorey, A. P. Balachandran, Arshad Momen +1
Lorentz symmetry forbids decays of massive spin-1 particle like the into two massless photons, a result known as the Landau-Yang theorem. But it is known that infrared effect…
Novel Studies on the η' Effective Lagrangian
A. P. Balachandran, T. R. Govindarajan, Amilcar R. de Queiroz
The effective Lagrangian for η' incorporating the effect of the QCD θ-angle has been developed previously. We revisit this Lagrangian and carry out its canonical quantization with…
Semi-superfluid strings in High Density QCD
A. P. Balachandran, S. Digal, T. Matsuura
We show that topological superfluid strings/vortices with flux tubes exist in the color-flavor locked (CFL) phase of color superconductors. Using a Ginzburg-Landau free energy we f…
Non-abelian Topological Strings and Metastable States in Linear Sigma Model
A. P. Balachandran, S. Digal
Non-abelian (NA) topological string defects exist in QCD with the spontaneous chiral symmetry breaking . Anomaly effects lead to domain walls…
Topological String Defect Formation During the Chiral Phase Transition
A. P. Balachandran, S. Digal
We extend and generalize the seminal work of Brandenberger, Huang and Zhang on the formation of strings during chiral phase transitions(berger) and discuss the formation of abelian…
Parity Doubles in Quark Physics
A. P. Balachandran, S. Vaidya
There are numerous examples of very nearly degenerate states of opposite parity in molecular physics. The ammonia maser is based on one such double. Theory shows that these parity…
Saha and the Dyon
A. P. Balachandran
Meghnad Saha occupies a special role in the history of Indian science, having been a pioneer in its organization already from the oppressive colonial period and having left importa…
